That's a good question,
Depends on how it's plumbed.
I was thinking of having the refrigeration
offtake first in the line because it needs the coldest coolant and in the grand scheme of things, doesn't make a lot of difference. Then the charge air cooler, then the AC and lastly the diesel
engine. Diesels don't like running on cold water anyway to it would be fine at the end of the line.
A variable speed pump would take care of the flow rate. These are old technology, very reliable and also cheap
. A spare pump carried aboard would take care of redundancy. Flow rate dictated by engine temperature I would think.
You wouldn't want anything plumbed in series. Parallel take off and return would allow flow rate for each device to be controlled by simply using a restrictor.
